DETAILED DESCRIPTION

[0025] Below, in conjunction with the accompanying drawings and specific implementation methods, the utility model is further described.

In the description of the present application, "plurality" means two or more, unless otherwise precisely and specifically specified.

[0027] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "connected", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, or it can be connected through an intermediary medium, it can be the internal connection of two elements or the interaction relationship between two elements.

[0028] like Figure 1-Figure 6 As shown, the waist support inner and outer frame installation structure of the embodiment of the utility model includes an inner frame 10 and an outer frame 20. The inner frame 10 is provided with a first connecting edge 11, and the first connecting edge 11 is provided with a plurality of first clamping members 111. The outer frame 20 is provided with a second connecting edge 21, and the second connecting edge 21 is provided with a plurality of second clamping members 212. When the outer frame 20 is assembled to the outer periphery of the inner frame 10, the inner side of the second connecting edge 21 of the outer frame 20 abuts against the outer side of the first connecting edge 11, and the second clamping members 212 are correspondingly clamped with the first clamping members 111.

[0029] On the basis of the above structure, when the lumbar support inner and outer frame installation structure is used for a seat lumbar support, the inner frame 10 and the outer frame 20 are assembled and then assembled with other structures of the lumbar support, so that the lumbar support with better support strength is formed.

[0030] If the inner frame 10 and the outer frame 20 are connected by structures such as screws or bolts, this will cause the screws or bolts to be exposed, and there will be too many external installation marks after assembly, affecting the overall appearance. Therefore, in this embodiment, when the inner frame 10 and the outer frame 20 are assembled, the first connecting edge 11 of the inner frame 10 and the second connecting edge 21 of the outer frame 20 are clamped by the first clamping member 111 and the second clamping member 212, and the clamping assembly structure is located on the first connecting edge 11 and the second connecting edge 21 to avoid the installation marks being exposed. The clamping assembly using the first clamping member 111 and the second clamping member 212 also reduces the use of external tools such as screwdrivers, simplifies the installation process, and facilitates disassembly and assembly.

[0031] In addition, after the inner frame 10 and the outer frame 20 are assembled, the first connecting edge 11 and the second connecting edge 21 abut against each other, which can increase the contact surface of the inner frame 10 and the outer frame 20 and improve the assembly stability of the inner frame 10 and the outer frame 20.

[0032] Furthermore, a third connecting edge 12 is provided on the inner frame 10, and the third connecting edge 12 is arranged opposite to the first connecting edge 11. The third connecting edge 12 and the first connecting edge 11 can be arranged opposite to each other vertically or horizontally. In addition, a second connecting edge 21 is arranged around the outer frame 20, and the outer frame 20 is connected to the outer periphery of the inner frame 10, and the second connecting edge 21 abuts against the first connecting edge 11 and the third connecting edge 12.

[0033] When the inner frame 10 is assembled to the inner periphery of the outer frame 20, the first connecting edge 11 and the third connecting edge 12 respectively abut against two opposite positions of the second connecting edge 21, and there are at least two larger abutting surfaces in the circumferential direction for restriction, so that the assembly is more stable.

[0034] A second clamping piece 212 is provided at the inner side of the top end of the second connecting edge 21, and a first connecting hole 211 is provided at the bottom end of the second connecting edge 21. For example, the first connecting edge 11 and the third connecting edge 12 are arranged opposite to each other up and down, and the third connecting edge 12 is provided with a second connecting hole 122. The first connecting edge 11 is located at the top end of the inner frame 10, and the third connecting edge 12 is located at the bottom end of the inner frame 10. When the inner frame 10 is assembled to the inner periphery of the outer frame 20, the first connecting edge 11 at the top abuts against the inner side of the top end of the second connecting edge 21, and the third connecting edge 12 at the bottom abuts against the bottom end of the second connecting edge 21.

[0035] When the inner frame 10 and the outer frame 20 are assembled, the first connecting edge 11 of the inner frame 10 can be first extended to the inner side of the top end of the second connecting edge 21 of the outer frame 20. At this time, the first connecting edge 11 and the top end of the second connecting edge 21 are snap-fitted, so the top end of the inner frame 10 is snap-fitted with the top end of the outer frame 20 to limit the position. The inner frame 10 can be rotated relative to the outer frame 20. After the inner frame 10 is rotated downward, the third connecting edge 12 abuts against the inner side of the bottom end of the second connecting edge 21. At this time, the second connecting hole 122 corresponds to the first connecting hole 211, and the first connecting hole 211 and the second connecting hole 122 are connected with a connecting piece, and the bottom ends of the third connecting edge 12 and the second connecting edge 21 can be locked by the connecting piece.

[0036] The first clamping member 111 and the second clamping member 212 are respectively provided on the upper side of the inner frame 10 and the outer frame 20 to limit the position, and the lower side is limited by the third connecting edge 12 and the bottom end of the second connecting edge 21 with the connecting member, and the upper and lower assembly structures are stable. Since the connecting member is extended from the first connecting hole 211 of the outer frame 20 to the first connecting hole 211 of the third connecting edge 12, the installation trace formed after the connecting member is assembled is located at the bottom end of the outer frame 20, rather than the front side of the outer frame 20, and the concealment is good and does not affect the appearance.

[0037] Furthermore, if the hole structure is directly processed on the second connecting edge 21, it is easy to have insufficient hardness after assembly. Therefore, in this embodiment, a protrusion block 213 is provided on the inner side of the bottom end of the second connecting edge 21, and the above-mentioned first connecting hole 211 is provided on the protrusion block 213 and penetrates the protrusion block 213, that is, the protrusion block 213 is provided at the position where the first connecting hole 211 is provided on the second connecting edge 21, so as to enhance the strength of this position and improve the assembly strength after the connecting part is assembled to the first connecting hole 211.

[0038] Of course, when the third connecting edge 12 is assembled to the bottom end of the second connecting edge 21, the protruding block 213 of the second connecting edge 21 can abut against the bottom end of the third connecting edge 12 to support the bottom end of the third connecting edge 12 and improve the assembly strength of the connection position.

[0039] More specifically, a reinforcing block 121 is provided at the top of the third connecting edge 12, and the second connecting hole 122 passes through the interior of the reinforcing block 121. Since the third connecting edge 12 extends out of the inner frame 10, the thickness strength is relatively weak relative to the inner frame 10 as a whole, and the second connecting hole 122 is provided on the third connecting edge 12, which may be unstable after the connecting piece is passed through. Therefore, the reinforcing block 121 is connected between the inner frame 10 and the third connecting edge 12 to strengthen the strength of the third connecting edge 12. At the same time, the above-mentioned second connecting hole 122 passes through the reinforcing block 121, and the connecting piece can be extended into the reinforcing block 121 when assembled, thereby improving the connection stability.

[0040] Furthermore, the third connecting edge 12 is arranged at an angle, so that when the third connecting edge 12 of the inner frame 10 is assembled to the bottom end of the second connecting edge 21 of the outer frame 20, the third connecting edge 12 inclined from top to bottom presses downward against the inner side of the bottom end of the second connecting edge 21 to reduce looseness after assembly.

[0041] The above-mentioned first connecting hole 211 and second connecting hole 122 are both threaded holes, and the corresponding connecting parts are screws. When the third connecting edge 12 is locked with the bottom end of the second connecting edge 21, the screw passes through the threaded hole of the outer frame 20 and is locked in the threaded hole of the third connecting edge 12, which is convenient for disassembly and assembly.

[0042] Of course, the above-mentioned connecting parts can also be bolts, rivets, expansion screws, etc. in the prior art, and can be selected according to actual needs.

[0043] Furthermore, the first clamping member 111 is a bayonet, and the second clamping member 212 is a buckle.

[0044] In this way, when the inner frame 10 and the outer frame 20 are assembled, the first connecting edge 11 of the inner frame 10 is extended into the inner side of the second connecting edge 21 of the outer frame 20, and the bayonet on the first connecting edge 11 is matched with the buckle on the second connecting edge 21, so that the buckle is snapped into the bayonet to realize the snap-fitting of the first connecting edge 11 and the second connecting edge 21.

[0045] Specifically, the buckle is arranged on the inner side of the second connecting edge 21. After the buckle is snapped into the bayonet, the snapping position is located on the inner side of the first connecting edge 11 and the second connecting edge 21. This can effectively reduce the exposure of installation marks and make the overall appearance more beautiful.

[0046] Of course, the first clamping member 111 may be a buckle, and the corresponding second clamping member 212 may be a bayonet. Alternatively, the first clamping member 111 and the second clamping member 212 may both be hooks that are engaged with each other.

[0047] Furthermore, the first clamping member 111 and the second clamping member 212 are provided in plurality. When the first connecting edge 11 and the second connecting edge 21 are clamped to each other, the plurality of first clamping members 111 and the plurality of second clamping members 212 are clamped to each other in a one-to-one correspondence, and the formed assembly structure is more stable.

[0048] The embodiment of the utility model also provides a seat, comprising the above waist support inner and outer frame installation structure. The other structures of the seat are the same as those in the prior art and will not be described in detail here.

[0049] Finally, it should be noted that the above-mentioned implementation modes are only optional embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
